On May 4, 2026 at 13:50 UTC, a magnitude 4.5 shallow crustal earthquake struck 58 km WSW of Masachapa, Nicaragua, at a depth of 50.4 km and coordinates 11.5237°, -86.9774°. This earthquake was detected by 67 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
